GLASS PLANT.

Specification of Letters Patent.

' Patented Ma. 7, 191a.

To all whom it may concern:

Be it known that I, LEOPOLD MAMBoURG,

a citizen of the United States, residing at Columbus, Franklin county, Ohio, have invented certain new and useful Improvements in GlassPlants, of which the following is a specification.

his invention relates to glass plants in which a large body of glass is held in melteddrawing-pot is disposed on trunnions in a,

pot-furnace; the charge dipped from the tank by a cooled ladle is delivered into the drawing-pot; the bait dips into the drawingpot and draws the cylinder; the drawing continues until the capacity of the drawing .motion is reached or until the glass in the pot is too cold for further drawing, notwithstanding the heat supplied by the potfurnace; the cylinder is cut off at its base and the afterbirth falls to the drawing-pot; 7

the drawing-pot, which is double faced is then reversed; a new charge is dipped from' the tank and delivered to the drawing-pot to be operated upon by the drawing machine as before; the cooled glass and afterbirth in the lower member of the reversed pot is fused out by the heat of the pot-furnace and drops therefrom; this discharged matter. is allowed to cool sufficiently to be transported;

it is then transported to the charging-opening in the tank for remclting. The tank is provided with suitable gas appliances and draft devices for melting the glass and crane facilities are provided for handling the la'dle.

In the system just described a reversible drawing-pot is required, and the glass dropped from the reversed pot must be and somewhat diagrammatic showing.

cooled prior to recharging, a very considerable loss of sensible heat in the glass resulting. Furthermore, the cooling and transportation of the waste glass from the drawng furnace to the distant end of the tank introduces the liability of such glass taking up lmpurities which may have a blistering eflect upon the ultimate glass production, and the-transportation of the dipped glass from the tank to-the drawing-pot involves similar liabilities, in addition to which there is an undesired disturbance of the glass in its discharge from thevdipper to the drawlng-pot, as wellas a material loss of temperature in the glass. I

In my improved plant I use the pot itself as a dipper, and I'provide for the getting of the waste glass from the drawing-pot back into the tank with a minimum loss of sensible heatand with a minimum chance for the gathering of impurities. I am here setting forth my improvements in a typical M improvements will be readily understood from the following description taken in con nection with the accompanying drawings in which Figure 1 is a front elevation 'of a potfurnace with its drawing-pot: Fig. 2 a vertical section of the same, viewed from the rear, in conjunction with a typical bait of plant, portions appearing in the plane ofline b of Fig. 6: and Fig. 6 a front elevation of one of the pot reheaters in conjunction wlth the tank, portions appearing in the plane of line 0 ofFig; 5.

In the drawings :1, indicates a drawingpot: 2, engaging devices upon the periphery of the drawing-pot to permit of the pot being grasped and handled. either side up, by means of suitable crane-supported tongs: 3, a pot-furnace adapted toreceive the pot in its upper portion: 4, piers in the potfurna'ce for the support of the pot: 5, the

, molten glass.

ten glasssis to have the bait of the drawing machine dipped 'down'into' the glass and draw upwardly therefrom the glass cylinder in the usual-manner, the heat supplied tothe .J

pot-furnace by thegas burning therein maintaining the glass 1n the :pot at vdesired Q-temperature, so far as is. feasible. If, 'a'sinay sometimes occur, there is any-sloppingover of glass from thedrawing-Pot it goes down into. the, pot-furnace and is discharged through the discharge hole 7 to be" dealt with in the usual manner, though in-many cases no glass will go from the drawing-pot to the pot-furnace. The draw will continue r until the ultimate draw has been reached or the glass in the pot has become too much chilled for further drawing. [Thedraw hav-' ing been completed, and the 'afterbirth cut off, the pot contains a mass of unusedand more or less chilled glass along with the afterbirth. The pot, with whatever glass it contains, is now to be withdrawn from the pot-furnaceand transferred to .a reheating furnace and inverted and the glass therefrom drained back into the tank, another part of molten" glass being brought to the pot furnace, ready for a new drawp My improvements contemplate anu'mber of potfurnaces and drawing machines, and a suf-' 40 ficient number of drawing pots to take care of all of the drawing machines.

Continuing with the drawings :--9, indicates the melting tank, which may be of usual construction and which should be provide'd with the usual heating and draft provisions: 10, the charging opening atthe heel of-the tank: 11, the nose ofthe tank from which the glass is to be dipped by the drawing-pots, this nose being illustrated as of T-form adapted to have glass dipped from its ,front or from its ends 12, openings in the nose of the tank at the ends and front of the extension 11, these openings being each of a size adapted to permit of a drawing-pot being introduced into. the tank through them: 13, reheating furna'cesat the chargin'gend of the tank; 14, openings in the reheating furnaces to permit the insertion therein of'the pots carried-thereto from the pot furnaces: 15, the sloping floors of the reheating furnaces, the same sloping downwardly toward the: tank 5 16, piers project-- rim downward in the reheating furnaces: 17, thebottom of apot disposed bottom up, in one of the reheating furnaces: 18, ducts leading ,from the reheating furnaces to the hates to the tank at a point not higher than 10' ;-'The drawin -pot with its charge of mol- 'iith'e'levelof-the-ino'lten glass in the tank: and

1 typifying gaspipes for supplying gas to he reheating furnaces.

In 'thefimproved plantthere may be any suitable-number pf drawing machines and ipot-:furiiaces,-' the nose of the tank, and the reheating "furnaces being designed accordingly.-- It is, ofcourse, be assumed that the openings in the tank will have the usual doors for closing them, and that the tank will-'beiprovided'with the heating and draft accessoriesiusual in connection with glassmelting tanks. nosetofxthe tank as-being provided with six In Fig. 5 I illustrate the of the openings 12 at-i ds and twelve of these-openings at itsfront, 'ving twentyfouriopeningsin all, and I have'illustrated the two reheating furnaces 13 as each being provided with six of theopenings 1 1 for the insertion and withdrawal of the drawing pots, and it is. to be assumed that suitable crane facilities will be provided for handling the tongs which grasp the drawing potsin dipping them into the tank and in placing them in the pot-furnaces and in removing them from the pot furnaces to the reheating furnaces. InFig. 5 I have shown one of the pot-furnaces at the left of the nose tions to which drawing machines, if port- I able, may be brought, and there may be as many of these pot-furnaces as is deemed advisable.

.Looking at Fig. 5 it is seen that the right hand one of the pot-furnaces 3 is idle,'that is to say, there is no pot in it. The pot is seen bottom up at 17 in the right hand reheating furnace. The reheating furnace is heated by gas and the same draft apparatus which draws on the melting tank draws through the reheating furnaces. Pot 17 may be assumed as having had all of the glass melted out of it and drained down into the .tank. This pot 17, or any other pot in either of the reheating furnaces may now, by

means of appropriate tong and crane facilities, be Withdrawn from its reheating fur nace and inserted into any one of the openings 12 in the nose of 'the tank and, by proper manipulatiombe employed as a dipper to gather from the tanka proper charge the tank, and no material liability for this" drawing. This pot is now taken from the pot-furnace and transported to and inserted intothe reheating furnace and turned upside down and rested on the piers 16, all the glass in the pot being melted out by the aCtlOll in the reheating furnace, the molten glass, flowing out of thereheating furnace and down into the tank, leaving the pot heated and in condition for the next dipping and drawing operation pertaining to that pot. When the pot is withdrawn from the reheating furnace and inserted into the tank for use as a dipper, it is in hot condition, and

when the pot, after the draw, is transported to the heating furnace. it carries with it all of the sensible heat of the glass within it,

' there thus being no material cooling of waste glass between the pot and its re-charge to waste glass to accumulate impurities which may affect the character of the glass. There may, if desired, be a pot-furnace and a drawing machine for each of the dipping openings ir the nose of the tank, or the general work of the plant may be carried on in such order that the pots are taken from pot,-

, furnaces to the reheating furnaces and then to dipping openings in the tank and then to pot-furnaces for drawing in such manner as may be found most expedlent. It might here be stated-that itis desirable to provide the molten glass in the tank with a float-ring to localize the portion of the glass which is to be withdrawn-from the tank in the operation of dipping it out by means of the pot, any overflow or spilling in the dipping operation being caused to drip to the main body 50 of the glass in the tank outside of the floatring. Such an equalizing float-ring 1S dls- -closed, in a general way, in Mambourg and Houzes Patent No. 970633 of September 20th, 1910.

\Vhile I have disclosed a glass plant of rather extended character suited for the employment of quite a number of drawing niachines and pots and potfurnaces, the fundamental principle of my improvements may be realized, to an extent, in case there is but a single drawingmachine and a single potfurnace and a single dipping opening in the ends of the tank,= and a reheating furnace adapted for the reheating of but one pot at a time. i The apparatus particularly set forth is to be considered as being merely an exemplification ofiny invention; I have sought to set forth the principle of my invention and the best mode-in which I at present contemplate embodying that principle.
